Subject Re: AMQ + Programmatic Creation of Destinations + Registration in JNDI
Date Tue, 04 Aug 2009 15:08:46 GMT

Hi Dejan - the below example will work fine, however, it doesn't solve our
need. We need to be able to create queues and topics programmatically
(createQueue) and I want to avoid having to write something out to
jndi.properties to do this. Also, most of our lookups currently have "/"'s
in the name and I found you can't easily do this, like: queue/domain/qname =
some/physical/name 


A little more background: we were using jboss mq to handle messaging, but
after some debate decided to move away. Jboss would force us to write out a
mbean xml containing the queue or topic and that would be accessible in jndi
lookups. I really like ActiveMQ but as I have said we have to be able to
create queues & topics in code and support the ability to find them by doing
jndi lookups -- without having to manually bounce the server or otherwise
append to some properties file. 

Hope that helps in clarity...
